（imx6）yocto修改qtbase添加编译tslib插件

1、添加tslib配置

相对位置：sources/meta-qt5/recipes-qt/qt5/qtbase_git.bb

添加：

git diff qtbase_git.bb
diff --git a/recipes-qt/qt5/qtbase_git.bb b/recipes-qt/qt5/qtbase_git.bb
index 4e1ab72..8a77aad 100644

2、修改tslib插件（触摸没旋转）

修改位置：fsl-imx-x11/tmp/work/cortexa9hf-neon-mx6qdl-poky-linux-gnueabi/qtbase/5.8.0+gitAUTOINC+49dc9aa409-r0/git/src/platformsupport/input/tslib/qtslib.cpp

   参考链接（https://forum.qt.io/topic/67820/cannot-rotate-my-touchscreen-with-qt_qpa_evdev_touchscreen_parameters-using-linuxfb-plugin/2）

生成补丁，添加到qtbase_git.bb

3、单独编译qtbase

bitbake -c compile -f -v qtbase

编译之前可以清一清

bitbake -c clean -v qtbase
